Checking the generator voltage limitation
The mechanical voltage limitation must be checked regularly.
1. Switch off all consumers.
2. Disconnect the plug of the actuator.
3. Connect an electrical voltmeter.
4. Start the generator.
5. Turn the actuator to the lowest limit point by hand. The max. voltage is 260 V (130 V).
6. The voltage must be 225 V (110 V).
7. Turn the actuator to the upper limit by hand. The max. voltage is 260 V (130 V).
8. A new adjustment is necessary in case of deviants.
B.4 Generator-Output Voltage is too low
If the AC generated is too low, then the consumers should be disconnected, one after the other, in
order to reduce the load on the generator. Generally the problem is then solved. The frequency
should be checked, if the output voltage is correct after the consumers have been disconnected.
Should this be above the prescribed generator idling speed, it can be assumed that one or
several condensers are defective.
B.4.1 Discharging the Capacitors
ATTENTION! Never work on the control box, if the generator is running!
Do not touch the capacitors contacts, see “Safety first” on Page 10.
1.Switch off the generator.
2.Remove the starter battery.
3.Open the AC-Control Box.
The capacitors are discharged by short
fusing both contacts. The contacts (Flat
plug) can be bridged by means of a
screwdriver with an insulated handle
(short-circuiting).
